派生 象征差异 该软件的原始版本由Andrew Clausen(位于econ.upenn.edu的clausen)于2007年用R编写。 Mark Reid(anu.edu.au上的mark.reid)发送了补丁,并于2009年2月2日发布。 2014年,安德鲁已将维护工作交给了Serguei Sokol(sokol,位于insa-toulouse.fr)。 从那时起,该软件就进行了深刻的重写和完善。 主要的新功能包括: 新的派生引擎,允许使用简单的语法来区分规则; 规则表中添加了许多新功能; 用户可以添加自定义区分规则; 具有多个分配运算符的代码的自动微分(AD); 当采用函数的派生时,Deriv()也返回一个函数。 可以使用与原始函数相同的参数来调用后者。 可以通过存储在向量或列表中的变量来区分,例如param$theta或x[1] , x[2]等。 简化扩展到有理
